What we do

Physical chemical properties and analytical methods department

Our team of experts brings many years of experience in different regulatory authorities and from the industry and covers all European zones with the different nationalities.

On the basis of a 5-batch analysis, we draw up legally compliant specifications of their active substances for our customers. This exact description is just as important for the establishment of a new production source for the European market as for the planned participation in a task force, which is regularly organised and accompanied by the GAB.

It does not matter whether the active substance is a chemical single substance, a natural or synthetic mixture of substances or a microorganism.

We can support you in the preparation of the corresponding parts of a registration dossier for new registrations or re-registrations of an active substance or a product and check the already existing physicochemical and analytical data for completeness. The performance of necessary GLP or non-GLP studies to complete your data set is reliably organised by us and accompanied during the performance. Depending on your wishes or requirements, we can prepare the summaries of the studies in Word or IUCLID format.

We have been working with reliable and first-class laboratories for years, both for the physico-chemical and the necessary pre- and post-registration analytical methods, in order to guarantee our customers a problem-free process.

Toxicology department

Our team of experts includes EUROTOX-certified toxicologist and approved university teachers in toxicology.

We can support you in:

Hazard assessment

  • Critical evaluation of available toxicological data (both chemicals and microorganisms)
  • Identifying which studies are required (based on regulatory data requirements)
  • Commission, design, monitor, summarize and interpret all types of toxicological studies according to relevant guidelines (in vitro, acute toxicity, repeated dose, reproductive toxicity; dermal absorption, genotoxicity, endocrine disruption)
  • avoiding studies, if possible (non-testing methods – QSAR or read across; science-based waivers and expert statements)
  • Classification and labelling according to Regulation (EU) 1272/2008 and relevant ECHA-guidance
  • Compiling full dossiers for active substances and/or products

Exposure assessment
Using the latest relevant exposure models following guidance and our experience we estimate the non-dietary exposure of operators, workers, bystanders, residents and the general public.

If needed, for higher tier refinement, we also design, commission and monitor field studies (DFR, DT50, Operator-, worker- or bystander exposure)

Risk assessment
Based on hazard assessment and exposure estimation a risk assessment is performed including risk management proposals.

Residues department

Our team of experts combines a broad experience of study performance and their regulatory assessment. We highly profit from our direct contact to field services and our long-term experience with regulatory authorities.

We can support you with:

  • Data gap analyses and advice on study requirements;
  • Planning, commissioning, monitoring and evaluating studies investigating the nature or magnitude of residues in plants, plant commodities or livestock;
  • The preparation of your residues dossiers for active substance approvals and product authorisations;
  • Consumer risk assessments following EU and national models for pesticides;
  • Exposure calculations for biocides;
  • MRL applications;
  • Scientific support with negotiations with authorities in pre-submission meetings or dossier defence activities;
  • Expert statements
Environmental fate

Our environmental fate team consists of competent and highly motivated experts with collective decades of experience in dossier preparation and exposure / risk assessment. We can support you in:

Dossier preparation

  • Data gap analyses including preliminary exposure and risk assessment
  • Dossier strategy and preparation for active substance approval and product registration
  • Expert statements (e.g. authority responses, justifying risk mitigation measures, defense of existing studies, or waive study requirements)

Exposure and risk assessment

  • Exposure and risk assessment for standard (e.g. agricultural field) and non-standard applications (e.g. non-professional use, greenhouse applications, fogging, post-harvest use, paddy field) including scenario development
  • Environmental modelling following registration requirements at EU and Zonal/MS level
  • Higher tier modelling (e.g. SWAN, VFSMOD, GeoPEARL, FROGS, customised exposure scenarios)

Study monitoring

  • Design and supervision of laboratory and field studies investigating the metabolism, degradation/dissipation or mobility of active substances or metabolites in all compartments
  • Higher tier studies (e.g. soil dissipation studies, guideline adaptations) including investigations of complex mixtures
  • Proficient in current and draft guidance (e.g. OECD, US-EPA, SETAC)

Data evaluation and preparation

  • Evaluation of laboratory and field studies (standard and higher tier)
  • Kinetic (re)evaluation following FOCUS kinetics
  • Normalisation of DegT50field values to reference conditions
  • Evalulation according to POP, PBT and vPvB criteria


  • Extensive experience with plant extracts, oily substances, inorganic substances and complex mixtures (e.g. UVCB) used as active substance
  • Internal QA by senior experts
  • Active participation in conferences and workshops
  • Knowledge management at all levels
  • Long-term contact with national authorities

Our multinational experts bring to the ecotoxicological team many years of very diverse experience from different fields such as contract research organisations or evaluating regulatory Authorities.

Our team can provide you with regulatory support in all the necessary steps starting from completeness check and ending up with dossier defence. We are involved on a daily basis in:

  • Detailed Data Gap Analysis including Preliminary Risk Assessments, including discussions on the strategy and evaluation of existing data
  • Providing advices on the strategies for possible testing and ecotoxicological risk assessment
  • Discussion and support in study designs, study monitoring and later study evaluation for standard and higher tier ecotoxicology studies
  • Literature researches
  • Meetings with Regulatory Authorities in different Member States
  • Ecotoxicological risk assessments including different tailor-project specific higher tier refinement options during dossier preparation
